The cis-enol form of β-diketones is characterized by a strong intramolecular hydrogen bond [1,2]. The formation of the hydrogen bond causes an increase in resonance conjugation through the resulting six-member chelating ...

From the theoretical point of view, 32 enol forms for FAA can be drawn, which only four cisenol

conformers have the six-membered chelated ring of the intramolecular hydrogen

bonding (IHB). For comparison, the ...

The most interesting thing in metal complexes of β-diketones comes up from their applications in science and industry. These compounds are frequently used in preparation of supported catalysts as precursors of heterogeneous ...

In this paper, molecular structure, relative stability and ligand-metal bond strength of bis (trifluoroacetylaceton) copper (II), Cu (tfaa) 2, have been investigated by applying density functional theory (DFT), Natural ...

-diketonates of various metals have been used in the preparation of supported catalysts and as precursors of heterogeneous catalysts

[1,2]. In this paper we synthesized bis(benzoylacetonato)copper(II), Cu(BA)2, by ...

The calculated bond lengths of Cu-O and O…O are shorter in Cu(DBM)2 than the corresponding ones in Cu(AA)2 and Cu(BA)2. The Cu-O symmetric stretching frequency is higher in Cu(DBM)2 than Cu(AA)2 and Cu(BA)2. Therefore, the ...

Fourier transform Raman (3200–150 cm−1) and infrared (4000–100 cm−1) spectral measurements have been made for the solid copper (II) benzoylacetonate, Cu(bzac)2 and, for comparison, copper (II) acetylacetonate, Cu(acac)2. ...

There are some discrepancies in both the vibrational assignments and in the metal–ligand (M–L) bond strengths predicted in the previous studies on the copper (II) chelated complex of dibenzoylmethane, Cu(dbm)2. Also, there ...

Proton having a small mass and radius shows various characteristic phenomena such as hydrogen bonding. Recently, many researches are devoted to very strong hydrogen bonds, because of their important role in biochemical ...
